I was on Tower ridge yesterday with Gareth and Alan for West Coast Mountain Guides. We made good time into the CIC hut but from there until we descended to the half way Lochan we couldn't see more than 20-30m. We could hear teams in Observatory gully but that was it. Tower ridge is very rocky at the moment and apart from the approach and one short patch we didn't really touch snow until the little tower. From here up the rock was coated in thawing verglas that was easily cleared. No photo's, there really was no point.
